I've designed a wallmount for the Teclast P40HD.
Bought it pretty cheap on Alie on black friday.

It's designed for wall outlets which have a pitch of 60mm for the screws
For example dutch wall outlets.

Needed other parts are:

• Longer M3 bolts for mounting back plate

• Magnets 4x2 mm ( for attaching the front plate to back plate ):

Optional parts for charging:

• USB - C flat cable 30cm :
  CAUTION link is for 20cm which is too short for my one, i've extended it with some wires :)

• Zigbee smart outlet with USB:

I've sacrificed a Zigbee outlet , dismantled it , cut some of the PCB and I've fitted in the wall outlet.
Intregrated it in Home Assistant to switch the USB port when battery is about 50% and charge it untill 80%
